AI Technical Summary

Technical Problem

The calibration method for existing powder material supply components is relatively cumbersome and requires repeated operations multiple times. The adjustment parameters mainly rely on manual operations, and both accuracy and speed are lacking.

Method used

A calibration method based on a detection device and a control unit is proposed, by detecting the strip height of the powder material in the supply step and the conveying step, automatically adjusting the tilt angle of the stacking plane of the supply device and the vibration frequency of the actuator to ensure that each supply device is supplied with the same amount of powder material per surface unit.

Benefits of technology

The rapid and precise calibration of the supply components is achieved, ensuring that all supply devices supply the same amount of powder material, reducing equipment downtime and manual operation requirements, and improving calibration efficiency and consistency.

Abstract

A method of calibrating a powder material (CP) feed assembly (8) comprising a plurality of feed devices (9) each having along its outlet (11) a plurality of operable dispensing elements (12) inclined at an angle (alpha) with respect to a horizontal plane. The calibration method comprises: a feeding step during which each feeding device (9) feeds a strip (SJ) of powder material (CPi) onto the conveyor (50); a conveying step of conveying the strip of powder material to a detection station (20); a detection step in which a detection device (19) detects the height of the strip of powder material; and an adjustment step in which at least the inclination angle (alpha) of the dispensing element (12) is adjusted on the basis of the data detected during the detection step such that all the strips (SJ) of the powder material (CPi) fed by the feeding device (9) have the same height. A manufacturing system (1) of ceramic articles (T) implementing the calibration method is also claimed.
