Abstract: A foundry sand reserving method includes reserving, acquiring, setting, and controlling. The reserving includes reserving foundry sand capable of being supplied to a foundry sand related device in at least one reserving unit. The acquiring includes acquiring a reserve amount of the foundry sand in at least one reserving unit, a charge amount of the foundry sand to the reserving unit, and a supply amount of the foundry sand to a foundry sand related device. The setting includes setting a threshold for the reserve amount based on a predetermined aging time of the foundry sand and the charge amount and the supply amount acquired in the acquisition step. The controlling includes controlling at least one selected from the group consisting of the charge amount and the supply amount based on the reserve amount acquired in the acquiring step and the threshold set in the setting step.

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.

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: Provided is a flask removal unit that removes a cope and a drag from an upper and lower flask. The flask removal unit includes a guide member, a flask moving unit, an extrusion unit, a support unit configured to move a support member together with an extrusion member to support the mold extruded from the upper and lower flask by the extrusion unit, and configured to convey the mold to an unloading position where the mold is unloaded, and a control unit. The control unit is configured to perform control such that at least one of an upper flask and an lower flask is moved to a position where the pattern member is able to be disposed between the upper flask and the lower flask in a period in which the support unit conveys the mold to the unloading position.
