摘要： A control device for an electric injection molding machine designed to advance and retract a screw in a heating cylinder by an injection motor includes a screw position detector for detecting a screw position to output a screw position detection signal, a speed pattern generator for generating a speed setting pattern signal which indicates relationship between time and screw speed. An integration unit integrates the speed setting pattern signal to obtain a moving stroke of the screw. And a generation unit generates a position instruction signal on the basis of the moving stroke and a screw position when injection is initiated. To generate a speed instruction signal, the screw position detection signal is subtracted from the position instruction signal as a manipulated variable of feedback and the speed setting pattern signal is applied to the position instruction signal as a manipulated variable of feed forward. Thus, accuracy at the speed changing positions can be improved, thus improving operability.

摘要： A method and apparatus for adjusting a zero point of a pressure sensor of an injection apparatus, which method and apparatus enable precise zero-point adjustment for the pressure sensor. Pressure of resin is detected by use of the pressure sensor, while a screw is moved, and a detection value corresponding to a detected pressure is obtained. The zero point of the pressure sensor is adjusted on the basis of the detection value. The detection value is obtained when the screw is moved in a state in which a flight speed is rendered lower than a screw speed. In this case, since the frictional resistance which acts on resin in the vicinity of the inner circumferential surface of the heating cylinder upon movement of the screw can be decreased, loads stemming from the frictional resistance are prevented from serving as disturbance against the detection value. As a result, zero-point adjustment for the pressure sensor can be performed precisely.

In addition, the controller rotates, in response to a pressure detected signal detected by a load cell, the screw in the opposite direction using a screw-rotation servomotor on and immediately after the completion of said plasticization and metering process to carry out depressurization of the molten resin in the heating cylinder that is metered ahead of the screw.

摘要： The invention provides a welding system capable of freely controlling the dispersion and concentration of arc heat over the groove face with an extreamly narrow gap and a high strength and high quality welded joint structure which is formed by this welding system and which is capable of preventing softening/hardening of the structure, the lowering of the toughness thereof and the generation of a crack. According to the welding system, the melting rate of a welding wire is controlled relative to the welding wire feeding rate by changing the characteristic of an arc current so that the range of behavior and the transfer rate of the arc pole (the arc generating main point at a groove surface) are controlled. Further, the welded joint structure consists of a high strength steel having a superfine grain structure with a carbon equivalent of as low as less than 0.38 and a crystal grain size of less than 7 μm and is welded by a consumable electrode type arc welding method so as to control the arc heat distribution on the groove face of the joint.

摘要： In a control system for controlling a motor-driven injection molding machine that comprises an injection unit driven by a servo-motor and a speed feedback control loop for controlling the servo-motor, an amplifier produces a command signal indicative of a torque command value for the servo motor in accordance with a difference between a sensed speed value obtained by a rotation speed sensor and a speed command value. A pressure sensor senses a pressure of resin within a mold to produce a sensed pressure signal indicative of a sensed pressure. A correction amplifier amplifies the sensed pressure signal to produce an amplified signal as a correction value for a torque command value. An adder adds the torque command value and the correction value to produce an addition result to a motor drive.
