Engraving machine and method for engraving building material articles, preferably slabs

Abstract

An engraving machine for engraving building material articles comprises a working plane (2) on which, in use, at least one building material article (S) or slab rests, and defining a working area having a predetermined width (W), an engraving device (4) facing the working plane (2) and equipped with at least one reservoir (7a, 7b) for containing an abrasive particulate material (M), and an array (8, 9) of nozzles (11, 12) for delivering the abrasive particulate material (M) configured for making a predetermined engraving path (E) on the article (S), and moving means (5) configured to determinea relative sliding between the working plane (2) and the engraving device (4) along a movement direction (A) transverse to the predetermined width (W). The nozzles (11, 12) of the array (8, 9) are arranged in succession along a direction transverse to the movement direction (A) in order to fully cover said predetermined width. A control unit (10) is provided, which is associated with the nozzles(11, 12) and configured to drive them independently of each other in order to adapt the engraving to the conformation of the predetermined engraving path (E).

Description

technical field

[0001] The present invention relates to a machine and a method for engraving an item of building material, preferably a slab.

[0002] Therefore, the invention has particular application in the field of the ceramics industry, especially in the production of engravings and / or textures on slabs or tiles by means of sandblasting. Background technique

[0003] In fact, in the ceramic industry or the marble industry, it is common practice to carve on slabs or tiles to produce specific patterns or pictures, and to try to treat them to produce, in whole or in parts, a texture that mimics the appearance of natural stone .

[0004] To achieve this goal, several solutions have been proposed over the years, mainly focusing on making engravings of different widths and / or depths on the exposed surface of the slab, most of which are based on the use of pre-cut or prefabricated pieces. Mask the shape to reproduce the processing to be performed.

Examples

Embodiment Construction

[0046] Referring to the drawings, numeral 1 designates an engraving machine for engraving items of building materials.

[0047] Preferably, the item "S" shown in the figures is a slab, preferably a ceramic slab.

[0048] For this reason, without loss of generality, the following description will explicitly refer to the slab "S" in place of the generic item; however, it will be apparent to those skilled in the art that everything that is structurally compatible with it is related to the slab items can be referred to as general items.

[0049] Preferably, the slab "S" is made of ceramic material or alternatively marble, stone or concrete.

[0050] The engraving machine 1 therefore finds a preferred application in the engraving of slabs for decorative purposes for creating pictures and reproducing the typical graphic effects of natural stone.

[0051] More specifically, the engraving machine 1 is configured to perform partial blasting of a slab, engraving the slab by a high-vel...
