摘要： A monitoring method capable of properly collectively managing the operating states and operation records of a group of injection molding machines. Monitor data sets delivered from the individual injection molding machines are cyclically detected by means of a processor of a monitor unit, and a plurality of sets of up-to-date monitor data for the individual injection molding machines are renewably loaded into a plurality of data tables. When the preset time of a timer associated with any one of the injection molding machines is up, or when the current injection frequency reaches a predetermined frequency, it is concluded that the monitor data output timing is reached, and whether the monitor data should be printed or displayed on a screen is further determined. In a print process or display process, the oldest data group, which includes the oldest monitor data set and the next oldest monitor data set or a combination of two these data sets and calculated monitor data variations associated therewith, is first printed or displayed, and similar data groups are successively printed or displayed by priority of oldness. When the print or display of the up-to-date data group, including the up-to-date monitor data set, is finished, a monitor data reload process is executed in order to update a plurality of monitor data sets to prepare for the next monitor data delivery.

摘要： A product acceptance/rejection judgment method which always ensures accurate judgment whether a product is acceptable or not even when an injection molding machine is operated in different operating environments is implemented by a processor (22) of a numerically controlled device (20). When the processor determines that it should perform, in addition to a normal product acceptance/rejection judgment based on molding process parameters, an auxiliary product acceptance/rejection judgment based on at least one operating parameter which directly indicates an injection molding machine operating environment characteristic involved in the acceptance/rejection judgment of the product, the processor reads output data from an A-D converter (11, 12 or 13) which data corresponds to the actual value of at least one operating parameter detected by an appropriate die temperature sensor (8), open air temperature sensor (9) or a wind velocity sensor (10). If an actual value of any one of the operating parameters deviates from the tolerance limit, and the processor determines that a molding failure may have occurred, the processor issues a failure signal. If all actual values of at least one operating parameter are within the tolerance limits, then the normal product acceptance/rejection judgment process is further implemented.

摘要： An article conformity discriminating apparatus for an injection molding machine is capable of automatically discriminating the conformity of articles with accuracy without using a conforming article sample. In molding cycles for mass production of articles executed according to optimum molding conditions of a mold file read from a shared memory (105), an actual resin pressure detected by a pressure sensor (4) is periodically sampled according to an output of an address generator (118), while a reference resin pressure sampled in the same sampling period or a corresponding sampling period on a pressure transition pattern, in a conforming article molding process for determining the optimum molding conditions made before the mass production of the articles, is read from the shared memory, (105) by a processor (114), and the actual resin pressure is compared with the reference resin pressure. If the absolute value of the difference between the values falls outside an allowable range, a defective sample counter value is incremented. When a hold process ends, a conforming article signal is sent if the counter value indicating the frequency of improper actual resin pressure generation is not greater than an allowable frequency, whereas a defective article signal is sent if the counter value exceeds the allowable frequency.

摘要： A method of monitoring a resin position intended to automatically display the relationship between the state of resin injected into the cavity and the screw position for monitoring. In the cavity, border sections where flow resistance of the injected changes are determined. Subsequently, a volume is found for each of the regions partitioned by the border, and the obtained volume is set into the control unit of the injection molding machine. The control unit displays the injection completion position when the amount of cushion Lc is inputted (200, 201). Moreover, the amount of a screw stroke Sj is determined on the basis of the volume determined for each of the positions having different flow resistance, and a screw diameter. Each amount of the screw stroke Sj is added to the amount of cushion Lc in sequence to find screw positions, which are to be displayed as injection speed changeover positions (203).

摘要： A product acceptance/rejection judgment method in an injection molding machine, which makes it possible to properly and quickly set judgment standard parameters and accurately judge whether a product is acceptable or not. Based on injection pressures and screw positions periodically sampled during each of a plurality of injection processes in nondefective product molding, an injection pressure curve group represented as a function of the screw position and an injection pressure curve group represented as a function of the time period elapsed from the start of injection are displayed on two coordinate systems (6, 7) on a display screen. Various reference values (x, p, t) and various upper and lower limit values (pu, pl, tu, tl, xu, xl) defining various permissible ranges for each of the screw positions and elapsed times that have been selected on the coordinate system are set in data display fields (8, 9), taking into account the distribution of the pressure curve groups and displayed contents shown in a data display field (10) and changing with movements of cursors (11, 12). During the execution of an actual molding cycle, each of the actual elapsed time period and actual injection pressure at each of selected screw positions, or each of the actual screw position and actual injection pressures at each of selected elapsed time periods is compared with its permissible range so as to check the acceptance/rejection of the same. Based on the resultant number of rejections, the conformity of a product is determined.

摘要： During a mold thickness adjustment process of an injection molding machine, a mold touch position at which the mold halves of a mold contact each other is detected, and the mold temperature is detected by means of thermocouples attached to the mold halves, respectively. Also, the mold thickness is obtained based on the position where a movable platen and a stationary platen of the injection molding machine contact each other, which is obtained previously, and the detected mold touch position.After a molding operation is started, the mold temperature (Tn1, Tn2) is detected in each of molding cycles, and the amount of change of the mold thickness (.DELTA.e) during the period between the preceding cycle and the current cycle is calculated (S14) based on the change of mold tempreature (.DELTA.T) during the period between the two cycles, the mold thickness (e), and the thermal expansion coefficient (k). The mold touch position for the current cycle (P) is obtained (S16) based on the calculated value. When the mold is clamped in the current cycle, the movable platen is moved from the mold touch position toward the stationary platen by a predetermined amount, to produce a predetermined mold clamping force.

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 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： An injection shaft of an electrically operated injection molding machine is entirely controlled based on its positions. In the injection process, an injection speed is changed over in accordance with a screw position for the processing at the injection process. In the subsequent dwell process, the screw is axially driven by a servomotor, a pressure applied to the resin is detected, and a difference between the pressure and a dwell pressure which has been set is found. The amount of movement in response to the difference is output to the servomotor for the drive thereof so as to keep the screw at the position. As a result, the dwell pressure is controlled by the screw position. Moreover, also in the metering process, the resin pressure is detected, and the screw is moved according to a difference between a set back pressure and a detected resin pressure so as to correspond with the back pressure which has been set. In this manner, the control of the dwell and back pressure can also be performed through the control of the screw positions, thus preventing the screw from substantially being displaced and largely deviating from the preset pressure at the time of the changeover of the pressure.

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.
