Definitions
- the present invention relates to a manufacturing system and a method for manufacturing articles made of compacted ceramic powder.
- production plants which supply (typically, in a substantially continuous manner) semi-dry ceramic powder (i.e., with a moisture content of below 10%, in particular ranging from 5% and 6%) along a given path through a continuous compaction assembly, which subjects the ceramic powder to a compaction pressure, so as to obtain a layer of compacted ceramic powder in the form of continuous strip of compacted ceramic powder, which is subsequently cut to obtain a plurality of articles made of compacted ceramic powder, having different sizes based on the type of ceramic product to be obtained, which will then be dried, possibly decorated, and fired to obtain the final ceramic products.
- semi-dry ceramic powder i.e., with a moisture content of below 10%, in particular ranging from 5% and 6%
- finishing stations also called deburring or trimming stations, at which the borders of the articles made of compacted ceramic powder are finished (or deburred) to eliminate the aforesaid burrs.
- finishing operations of the transverse and longitudinal borders of the articles made of compacted ceramic powder are carried out by means of abrasive tools that intercept the border to be treated, remove any excess material and bevel the edges of this border.
- Each of these abrasive tools is typically mounted on a linear guide arranged above the conveyor device intended to transport the articles made of compacted ceramic powder from the cutting station towards the subsequent processing stations, so that this abrasive tool moving along the respective linear guide can intercept and finish (i.e., deburr or trim) at least one border of an article made of compacted ceramic powder, when this article is above the conveyor device at the finishing station, so as to finish this border, that is, so as to remove any excess material (namely, the so-called burrs) from said border and to bevel the edges of this border.
- finish i.e., deburr or trim
- the finishing assembly To finish (i.e., deburr or trim) all the borders of each article made of compacted ceramic powder, the finishing assembly generally has two linear guides arranged parallel to the moving direction of the articles made of compacted ceramic powder to finish (i.e., deburr) the lateral borders of each article made of compacted ceramic powder while it moves (moved by the conveyor device) in the moving direction; and at least one further linear guide arranged crosswise to the moving direction to finish the front borders of the same article, when this is in a first position, and the rear borders of the article, when this is in a second position. Processing of the transverse borders of each article made of compacted ceramic powder is more complex and requires more time with respect to the longitudinal borders.
- the article made of compacted ceramic powder is stopped at the first position at least for the time required by the abrasive tool to process the front borders and in the second position for the time required by the abrasive tool to process the rear borders.
- the finishing (i.e., deburring) stations risk representing a bottleneck for the manufacturing plant of ceramic products.
