Abstract: A core inspection device for inspecting a core, the device including a color sensor configured to detect a measured value of each color component of the color of the surface of the core, and a determination unit configured to compare the measured value of at least one color component detected by the color sensor with a threshold prepared corresponding to the at least one color component, thereby determine if a strength property of the core is acceptable or not.

Abstract: Providing a method for reducing occurrences of a mold shift of a cope and a drag that have been molded by a flaskless molding machine and have been assembled by estimating a cause of a mold shift based on measurements and by taking appropriate measures, and a flaskless molding line that uses the method. The method for reducing occurrences of a mold shift of a cope and a drag (1, 2) that have been molded by a flaskless molding machine (200) and have been assembled comprises a step of measuring specific data at positions where a mold shift may occur during a process for manufacturing or taking out the cope and the drag, and a step of determining if the obtained specific data are within an allowable range.

Abstract: A method is provided for measuring a shift between a carrier for a pattern (a carrier plate) and a flask and preventing a defect caused by a shift in the cavity parts. The method for preventing a defect caused by the shift in the cavity parts in molding a cope and a drag with flasks by using a cope flask (110) that is assembled with a carrier plate (130) for the cope flask and a drag flask (120) that is assembled with a carrier plate (140) for the drag flask, comprises the steps of measuring a shift between the carrier plate (130) for the cope flask and the cope flask (110), measuring a shift between the carrier plate (140) for the drag flask and the drag flask (120), measuring a shift between the cope flask (110) and the drag flask (120) that have been assembled, determining if a shift in cavity parts is within an allowable range, wherein the data on the shift is obtained based on the shift between the carrier plate (130) for the cope flask and the cope flask (110), the shift between the carrier plate (140) for the drag flask and the drag flask (120), and the shift between the cope flask (110) and the drag flask (120, that have been assembled.

Abstract: An object is to accurately estimate loss-on-ignition in a short time. A loss-on-ignition estimation apparatus includes at least one processor configured to carry out an estimation step, the estimation step including estimating the loss-on-ignition of foundry sand with use of a learned model constructed by means of machine learning. The learned model is configured to receive, as input, (1) sand weight data relating to a weight of the foundry sand detected in a calcination period and (2) at least one of (i) sand property data relating to one or more properties of the foundry sand, (ii) additive data relating to one or more additives added to the foundry sand, and (iii) calcination environment data relating to a calcination environment detected in the calcination period. The learned model is configured to generate, as output, an estimated loss-on-ignition of the foundry sand.
