The foundry production line includes a sand moulding machine, a melt pouring device, a shakeout machine, a finishing apparatus, an inspection station and a computer controlled database system. A pattern plate is provided with a sand mould identification device including a plurality of individually adjustable indicator elements adapted to impress an identification pattern in a sand mould part. Each indicator element has rounded edges and indicates a direction. An automatic image detection system includes an imaging device arranged at the inspection station and being adapted to provide a digital image of an individual identification pattern formed in a cleaned casting. The automatic image detection system includes a computer system running a computer program developed by means of machine learning to analyse the digital image and thereby detect the individual identification pattern.
A foundry production line including a sand moulding machine, a melt pouring device, and a shakeout machine for breaking apart sand moulds and taking out castings, the sand moulding machine including at least one moulding chamber in which at least one pattern plate is adapted to form a pattern in a sand mould part during compaction of the sand mould part in the at least one moulding chamber, at least one pattern plate being provided with at least one sand mould identification device including a plurality of individually adjustable indicator elements adapted to impress an identification pattern in the sand mould part during its compaction, each individual indicator element being formed at an end of a rotationally arranged cylindrical element, a rotational position of each individual indicator element about an axis of rotation of the corresponding cylindrical element being adjustable by means of an actuator being controlled by a controller adapted to provide each sand mould formed by two sand mould parts with at least one individual identification pattern arranged to form a corresponding individual identification pattern in a resulting one of the castings, the foundry production line including an automatic image detection system adapted to detect the resulting individual identification patterns in the castings, and the foundry production line including a computer controlled database system adapted to store data relating to a number of production variables measured and/or set during production and data relating to the quality of the produced castings, wherein each individually adjustable indicator element is formed with rounded edges and is formed to indicate a direction along a diameter of the corresponding cylindrical element on which it is arranged, wherein the foundry production line includes a finishing apparatus adapted to clean the castings and an inspection station for inspection of the castings being arranged after the finishing apparatus in a transport direction of the castings, wherein the automatic image detection system includes an imaging device arranged at the inspection station, wherein the imaging device is adapted to provide a digital image of a particular one of the individual identification patterns formed in a cleaned one of the castings, and wherein the automatic image detection system includes a computer system adapted to run a computer program developed by means of machine learning to analyse the digital image and thereby detect the particular individual identification pattern of the cleaned casting.
A method of operating a foundry production line, whereby sand moulds are produced in a sand moulding machine, melt is poured into the sand moulds in a melt pouring device, and sand moulds are broken apart and castings are taken out in a shakeout machine, the sand moulding machine including at least one moulding chamber in which at least one pattern plate forms a pattern in a sand mould part during compaction of the sand mould part in the moulding chamber, at least one sand mould identification device including a plurality of individually adjustable indicator elements providing a corresponding identification pattern in each sand mould before melt is poured into the sand mould, each individual indicator element being formed at an end of a rotationally arranged cylindrical element, a rotational position of each individual indicator element about an axis of rotation of the corresponding cylindrical element being adjusted by means of an actuator being controlled by a controller so that each sand mould formed by two sand mould parts is provided with at least one individual identification pattern which subsequently forms a corresponding individual identification pattern in a resulting casting, whereby an automatic image detection system detects the resulting individual identification patterns in at least some of the castings, and whereby a computer controlled database system stores data relating to a number of production variables being measured and/or set during production and data relating to the quality of the produced castings, wherein each individually adjustable indicator element is formed with rounded edges and indicates a direction along a diameter of the corresponding cylindrical element on which it is arranged, wherein the castings are cleaned in a finishing apparatus, wherein the castings are inspected in an inspection station after being cleaned in the finishing apparatus, wherein an imaging device of the automatic image detection system is arranged in the inspection station and provides a digital image of the individual identification pattern formed in at least some of the cleaned castings, and wherein a computer system of the automatic image detection system runs a computer program developed by means of machine learning and thereby analyses the provided digital images and detects the individual identification patterns of the respective cleaned castings.
