Abstract: [Problem] To provide a method and device that automatically detects misalignment during flask mating in an automatic flask mating device for molding flasks for casting.[Solution] In an automatic flask mating device, an external force applied to a cope with a cope molding flask M1 during flask mating is detected by means of a physical quantity detection sensor 60, quantified by a computation/storage/determination processing device 61, and then compared with a numerical value at a normal time for determination to thereby determine whether the flask mating has normally completed and detect flask mating misalignment. A force sensor is preferably used as the physical quantity detection sensor.

Abstract: A method for detecting powder is performed in a powder detection device including a pair of electrodes arranged to be opposed to each other with a gap interposed therebetween and an electric circuit electrically connected to the pair of electrodes. The method includes detecting powder filling in a case where the electric circuit together with powder and the electrodes forms a closed circuit when the powder fills the gap.

Abstract: A strain element (10), which is configured such that a frame portion (11) and a central portion (12) are connected by arm portions (20) to (22), is masked except for the arm portions (20) to (22) where a strain gauge (A1) and the like are to be disposed, and then peening is carried out. With this, a compressive residual stress layer is formed on four sides of each of the arm portions (20) to (22). When the strain element (10) receives a load resulting from an external force, the arm portions (20) to (22) elastically deform; however, due to the compressive residual stress layer thus formed, the arm portions (20) to (22) are less prone to fatigue failure. When projection of a shot material is carried out as peening, the surface roughness of the arm portions (20) to (22) increases, the adhesion of strain gauges improves, detection accuracy improves, and stable measurement can be ensured.

Abstract: The present invention improves the reliability of a force sensor in terms of mechanical troubles. The force sensor includes: a primary bridge circuit that includes a first strain gauge group disposed on a first main face of a strain element and that is configured to detect a component, in a specific direction, of a force exerted on a strain element; and a secondary bridge circuit that includes a second strain gauge group disposed on a second main face of the strain element and that is configured to detect a component of a force in the same direction as the specific direction.

Abstract: [Problem] To provide a main mold and core setting device and a main mold and core setting method which enable core setting work, hitherto implemented by a core setting operator using subtle hand sensation, to be completely reproduced by automation.
[Solution] The present invention is provided with: a core grasping and moving means for grasping and moving a core; a core movement amount detection means for detecting a movement amount of the core grasping and moving means; a grasped core position and posture detection means for detecting a position, orientation, and inclination of the core grasped by the core grasping and moving means; a main mold position and posture detection means for detecting a position, orientation, and inclination of a main mold; a sensor for detecting a physical quantity applied to the core; and a control means for constantly calculating relationships between relative positions, orientations, and inclinations of the main mold and the core, and from these relationships and the physical quantity applied to the core detected by the sensor, controlling the core grasping and moving means so that the core is caused to set with the main mold.-

Abstract: A wear detection method and system for a linear actuator such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or the like. A physical amount detection sensor 9 is mounted on a linear actuator in which a push-pull member connected to a rod 2 pushes and pulls a pressure-receiving object while applying a lateral load in a direction different from the linear movement direction. An external force that is generated between a tube and the mounting member when the pressure-receiving object is pushed and pulled is detected by the physical amount detection sensor 9 and compared with standard external force data, which was detected in a state without abnormalities and stored in a computation/storage/determination processing device 10, to computationally determine whether the linear actuator is in a normal state or an abnormal state.
