    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.

  • Publication number: 20190195732
    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.

  • Patent number: 8786240
    Abstract: The invention realizes a method for controlling an electric cylinder and a control system for the cylinder that can prevent a load for pressurizing from significantly exceeding a target load and can shorten the time for the pressurization. A servo controller 17 can set the speed of the rod 11 and a load for stopping Ps that is used for determining whether the rod 11 should be stopped so that the load for pressurizing Pm does not significantly exceed the target load Pt. The servo controller 17 drives the rod 11 under the position control mode and determines whether the load for pressurizing Pm that is detected by a load detector 13 is bigger than or equal to the load for stopping Ps.

  • Patent number: 8749180
    Abstract: The present invention is aimed to realize a method and a system for controlling an electric cylinder by which the load detector that is attached to an electric cylinder and the rod of the cylinder can avoid being overloaded. An unexpected bump between the rod of the cylinder and the material to be pressed can cause that overload. A servo controller 17 determines whether the load for pressurizing Pm detected by the load detector 13 is larger than or equal to the load for detecting a bump Pc. If it is determined that the load for pressurizing Pm is larger than or equal to the load for detecting a bump Pc, the servo controller 17 determines whether the flag for stopping is ON. Also, the controller 17 determines whether the speed Sm of the rod 11 is greater than or equal to an allowable speed to bump Sc.
