Patent number: 5792395Abstract: A plasticization control method for an injection molding machine in which the plasticized state of resin in an injection cylinder is controlled in measuring based on the detected rotating force of a screw. A reference screw rotating force C or F required for desired measuring operation is determined. Using the reference screw rotating force C or F as a reference, upper and lower limits D and E of an allowable screw rotating force range, in which measuring can be performed normally, are set for each of screw positions, and then stored as an allowable value file. The rotating force V acting on the screw during measuring operation is successively detected. If the rotating force V is not between the upper and lower limits D and E of the allowable range relating to the current position of the screw, it is judged that plasticization is abnormal and an abnormality alarm is outputted.Type: GrantFiled: March 23, 1995Date of Patent: August 11, 1998Assignee: Fanuc Ltd.Inventors: Susumu Ito, Katsuyuki Yamanaka

Patent number: 5567367Abstract: An average is obtained between output readings of a pressure sensor obtained when forward and reverse thrusts are applied to an injection screw by positively driving a servomotor for injection. The average value is used as a correction value for a reading deviation of the pressure sensor. The injection servomotor is positively driven to apply a thrust to the screw. This known thrust and the actual reading of the sensor are compared. A deviation between these values is used as the correction value for the reading deviation of the sensor.Type: GrantFiled: January 23, 1995Date of Patent: October 22, 1996Assignee: Fanuc LimitedInventors: Susumu Ito, Masao Kamiguchi, Masato Yamamura, Noriaki Neko, Tatsuhiro Uchiyama, Yuichi Hosoya, Nobuto Takeda, Kaoru Hiraga

Patent number: 5279778Abstract: A positioning correction method for a motor-operated injection molding machine, intended to eliminate waste of power supply to or overheat of servomotors by locking up in an ideal state the motor-operated injection molding machine, which uses a toggle mechanism or crank for mold clamping and other operations. During the lockup period, a load RA acting on a mold clamping servomotor 7 is detected (S8), and a position command value PM for the servomotor 7 is increased or decreased in the next cycle in a direction such that the value of the load RA is reduced, if the value of the load RA is greater than a preset reference value V0 (S12, S13). As a result, a rotation center Q1 of a crank 2 and two opposite ends Q2 of a link 3 are locked up in a straight line, so that a moment of rotation produced by a mold clamping reaction force is removed from the rotation center Q1 of the crank 2.Type: GrantFiled: February 10, 1993Date of Patent: January 18, 1994Assignee: Fanuc Ltd.Inventors: Takayuki Taira, Susumu Ito, Masao Kamiguchi, Minoru Kobayashi, Ryuji Tai
