Latest Patents

Matsuda holds a patent for a "Control method and equipment for charging ready-mixed concrete additives." This invention focuses on a control method for charging additives batchwise, aiming to maintain the slump of ready-mixed concrete within a specific range. The method allows for longer transportation times by truck mixers without compromising the quality of the concrete. The slump is detected electrically as a change in mixing torque, and when the detected value reaches a predetermined threshold, a motor receives a control instruction to charge the necessary additives. The operating time of the motor and the interval until the control operation is reset can be adjusted with a timer. This innovative solution enhances the efficiency and quality of concrete delivery.
