    Abstract: A control method for an injection molding machine including a measurement process of measuring molten resin by moving a screw backward while rotating the screw in a heating barrel for melting a resin material, a rotational speed of the screw is reduced from a timing when a backward movement speed of the screw is reduced at the measurement process before the measurement process is completed, for stopping backward movement of the screw when the measurement process is completed, and the rotational speed and a rotation direction of the screw are controlled such that a back pressure as a pressure of the molten resin measured at the measurement process becomes a target pressure lower than the back pressure of when the measurement process is completed, when a target time comes.

    Abstract: The invention is to provide an in-line screw type injection molding machine which can have a simplified configuration of an injection mechanism and a metering mechanism. The in-line screw type injection molding machine is characterized by comprising: a metering motor 9 which rotationally drives a rear end side of a screw; a screw mechanism which includes a nut body rotating integrally with the screw, and a screw shaft fitted to the nut body, the screw mechanism converting rotational motion of the screw shaft into linear motion of the screw through the nut body; an injection motor 16 which rotationally drives the screw shaft; an injection motor drive circuit which drives the injection motor 16 to allow a position of the screw to follow a predetermined position command pattern; a metering motor drive circuit which drives the metering motor 9 to allow rotation of the metering motor 9 to follow a predetermined speed setting pattern; and an adder-subtracter circuit which adds or subtracts a speed setting pattern signal of the metering motor drive circuit to or from a speed command signal of the injection motor drive circuit so as to compensate an axial displacement of the screw caused by the rotation of the metering motor 9.

    Abstract: The exact method with small time-lag of detecting screw back pressure for controlling the screw back pressure in the plasticizing process of an electric-motor driven injection molding machine without using a pressure detector has been asked for because the pressure detector is very expensive, necessitates troublesome works for mounting, an electric protection against noise and the works for zero-point and span adjustings and causes a complicate mechanical structure.The present invention uses a high-gain observer which contains the discrete-time arithmetic expressions derived from a mathematical model of a plasticizing mechanism in an electric-motor driven injection molding machine consisting of state equations and outputs an estimate of screw back pressure, which is one of the state variables of the above state equations, by using a screw position signal, a servomotor current demand signal or actual motor current signal and a screw revolution speed signal as inputs. The high-gain observer obtains the exact screw back pressure estimate with very small time-lag without using a pressure detector. Thus the estimate of screw back pressure fed by the high-gain observer can be adopted as a feedback signal of actual screw back pressure for controlling the screw back pressure in the plasticizing process.

    Abstract: A measurement control method uses an ending target position Xes calculated by adding a prescribed length Ls to a measurement ending position Xe. A rotation rate pattern Ar for rotating a screw 2, a back pressure Ps in relation to the screw 2, and a retraction rate pattern Ab for the screw 2 to retract, are set in advance. The remaining rotation rate pattern Ar to stop the rotation of the screw 2 at the ending target position Xes from the detected screw position X, is calculated at the time of measurement, and the rotation of the screw 2 is stopped based on the calculation. Further, the remaining retraction rate pattern Ab is calculated from the detected retraction rate Vd, and the retraction of the screw 2 is stopped based on the calculation. The result is the stopping of the screw at the measurement ending position Xe.
