Definitions
- the present invention refers to an automatic control system of press compaction, being especially applicable to the manufacture of tiles and pavements.
- pieces are produced in dry presses, compacting a granulate material with a specific moisture, to thus attain solidly compacted pieces that endure, after being pressed, drying, enameling, painting, belt conveyance treatments, etc., even kiln firing, where they receive, by means of high temperatures, the definitive feature and resistance.
- the homogeneity of the product with regard to correct compaction is very important for the physical resistance of the pieces during the drying and firing process and when a product contracts during firing, it is even more important, since any difference of compaction would cause contraction differences, in other words, deformed pieces would be produced.
- the purpose of this invention is to attain an automatic control system of compaction and at the same time rapid, without the need of taking samples.
- very reliable and exact control of production can be achieved, since upon continuously having data after each pressing, statistically based decisions may be made, elaborating values based on many consecutive pressings, and in the event of adjustment by means of an intelligent feed slide, the load correction orders will also be considered on the grounds of many consecutive pressings and the possibility of mistakes upon processing non-representative values is eliminated.
- Patent of invention number P-8901208 also of the same applicant firm, refers to an intelligent feed slide to carry out the correction of load of ceramic material on the basis of a series of samples taken by hand.
- the automatic control system of press compaction that is the object of the invention, makes it possible to obtain data about the compaction directly when pressing takes place by distribution of pressure sensors installed in the press mold itself.
- pressure or force sensors are installed in a mold punch, which may be a top or bottom punch.
- the sensors measure the reactive force of the granulate material. Where there was a denser load, the compaction will logically be greater and the sensor in such an area will measure a higher force. Likewise, when it is an area with a smaller load, the compaction will be less and the sensor will measure a smaller force.
- the sensors communicate the force measured in current or voltage differences and an amplifying system converts these values into signals for a computer where the data will be processed to elaborate statistical values, etc.
- a data package is elaborated and sent by communication cable to the microprocesser control of the intelligent slide to correct defective load areas.
- FIGS 1 and 2. They schematically show the automatic control system of press compaction, when the sensors are located in the top punch and the positions before and after compaction, respectively, have been represented.
- FIGs 3 and 4.- They are schematic views similar to figures 1 and 2, with the sensors installed in the bottom punch.
- References (6) and (7) respectively show the supports for the top punch (2) and bottom punch (5.)
- This force is measured in voltage differences, and an amplifying system converts these values into signals for a processor, in such a way that the data are processed to elaborate statistical values, etc. thus continuously informing about the pressing quality.
