摘要： The position of a feed shaft is monitored, the mean moving speed and moving frequency of the feed shaft are measured with every unit time for position correction, and a correction amount &dgr;n is determined from the speed and frequency according to an approximation formula and updated (c7 and c8). A position correction amount for a commanded position is determined from this correction amount, and the commanded position is corrected by the position correction amount (c1 to c6). The position correction amount for the commanded position is determined from this correction amount, and the commanded position is corrected by this position correction amount. Since the correction amount is determined according to the approximation formula, thermal displacement correction can be effected at all times without requiring any sensor. When the correction amount changes substantially (c10), the thermal displacement is measured by means of a sensor and used as the correction amount (c11 and c12), whereby accuracy is improved. The frequency of measurement by means of sensors is reduced, so that the machining time can be reduced.

摘要： An operating time analyzing apparatus capable of automatically determining, storing, and analyzing the operating time of an injection molding machine for each operating condition. This apparatus detects the operating conditions of the injection molding machine through internal processing with a PMCCPU 14 for the sequence control of the injection molding machine. While specific operating conditions are detected, fine times .DELTA.t, execution cycles of the internal processing, are added in succession. By doing this, integrated time for each operating condition, that is, operating time for each operating condition, is calculated. This operating time is stored in a nonvolatile RAM 8 for each operating condition of the injection molding machine through the processing by the PMCCPU 14. The respective time-based ratios of the individual operating states and the like are calculated on the basis of the correlation between the operating times stored for the individual operating conditions, and displayed, along with the operating times for the individual operating conditions, with a CRT display unit of a manual data input device 18 corresponding to the operating conditions of the injection molding machine.

摘要： A programmable logic controller capable of freely and sequentially controlling peripheral equipment without modifying a system program. Necessary data for sequence control of the peripheral equipment are selected from data defined in the system program. The memory addresses corresponding to the data are assigned to addresses to be used in a user program in an address storage unit. The controller executes the system program to sequentially control an industrial machine, and also executes the user program to control the peripheral equipment. The controller refers to the data being used in executing the system program, which are necessary for sequence control of the peripheral equipment, based on the designated relationship of the addresses stored in the address storage unit. Since necessary data for sequence control of the peripheral equipment can be obtained by combining the addresses arbitrarily by the user, it is not necessary to modify the system program in order to obtain the necessary data for sequence control of the peripheral equipment.

摘要： Actual machining positions P1, P2, . . . corresponding to command positions S1, S2, S3 . . . of each block of NC data are obtained by trial machining. Positions that correspond symmetrically to the actual machining positions P1, P2, . . . with respect to the command positions S1, S2, S3 . . . of each block are obtained. Modified NC data are created with use of the symmetrical positions as modified command positions for each block. The modified NC data include correction values for modifying positional differences attributable to a delay in a servo system. Therefore, if machining is carried out in accordance with the modified NC data, the correction values and a follow-up delay attributable to the actual delay in the servo system cancel one another, so that a high-accuracy work shape can be obtained.

摘要： A zero point adjusting method and apparatus for a pressure detector of an injection molding machine, capable of carrying out a zero point adjustment of the pressure detector when external loads acting on the pressure detector are completely removed without disassembling an injection mechanism. An advance limit position Qf and a retreat limit position Qb of a screw are detected by driving the screw with a low output to determine an intermediate position Pm. By moving the screw to the intermediate position Pm, a resin reaction force acting directly on the screw is removed. Reciprocating motion in which an amplitude decreases gradually is imparted to the screw, thereby causing a backlash, having equal plays in the advance and retreat directions, between a ball nut and a ball screw. Then, the zero point adjustment of the pressure detector is made.

摘要： 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.

摘要： 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. In this manner, the mold clamping reaction force can be maintained during the lockup period without applying a driving torque to the mold clamping servomotor 7 by energizing the same. Thus, not only the waste of power can be prevented but also the load on the mold clamping servomotor 7 can be reduced, thereby unnecessitating the use of a stopper or other means for maintaining the mold clamping reaction force.

摘要： A resin flow analysis in a die is performed by CAE or the like to obtain a resin pressure curve at a resin inlet port or a resin pressure curve at a nozzle end portion of a molding machine. Injection (air shot) is performed while a nozzle is separated from a die, so that an injection pressure curve Pa to be detected at this time is obtained. From the injection pressure curve and the resin pressure curve, an injection pressure command curve serving as a molding condition in mass production is obtained. The resin pressure curve obtained by the resin flow analysis is compensated by the injection pressure curve in an air shot for a time lag and pressure loss caused by the mechanical elements of an injection molding machine, so that molding conditions in mass production can be easily obtained. In addition, a pressure loss at the nozzle portion is also obtained, so that an injection pressure command curve is obtained from the pressure loss, the injection pressure curve, and the resin pressure curve.

摘要： A temperature control method for an injection molding machine capable of performing stable temperature control at all times irrespective of the heat capacity of an object of temperature control. A temperature of an object of temperature control, such as a heating region of an injection cylinder, an injection nozzle and a mold, is detected by a respective temperature sensor G1-Gn. A feedback control of temperature is performed by a servo CPU (24) so that the detected temperature coincides with a set temperature, to obtain an electric current command value. Further, an actual electric current flowing in each of heaters H1-Hn is detected, and a feedback control of electric current is performed so that the actual current coincides with the current command value obtained by the temperature feedback control. Thus, stable temperature control is realized with less fluctuations of the electric current flowing in the respective heater H1-Hn and less fluctuations of the temperature of the object of temperature control in comparison with on/off control method.

摘要： A discrimination method for maintenance timing for injection molding machines, detects the respective values of molding process parameters of a plurality of types, including injection time, maximum injection pressure, etc., for each of the injection molding machines (7-1 to 7-M). Up-to-date process parameter values for the molding machine are entered as a set of monitor data in a molding monitor unit (1) every time a predetermined number of molding cycles are executed in each molding machine. A plurality of monitor data values for each type are read, on a time-series basis, from a memory (4) loaded with a plurality of sets of up-to-date monitor data values associated with each molding machine, by means of a microprocessor (2), and dot-line data are generated. Based on an approximate equation of the first degree indicative of the transition trend of each type of monitor data obtained using the dot-line data, an estimated value of the monitor data for a point in time after the present point of time is calculated. A warning message to demand the maintenance of an expendable part of the injection molding machine associated with the monitor data is displayed on the screen of a display unit (6) when it is concluded that the estimated value deviates from an allowable range for the monitor data. Thus, maintenance timing for the injection molding machine can be confirmed without disassembling the injection molding machine.
