Abstract: Provided are a mirror-surface member configured to reflect an insert held by an insert moving means and an insertion position compensation means. An amount of misalignment between the insert and the insert moving means is calculated based on a photographed image of the insert reflected on the mirror-surface member, and an insertion position for the insert to be inserted into a mold is compensated based on the amount of misalignment.

Abstract: An injection molding system includes a sensor that detects a state of a purged molding material, and a purged material analysis unit that obtains a detection signal of the sensor and analyzes the purged molding material. Whether or not the purge operation is completed is determined based on the detection signal of the sensor so as to complete the purge operation. The purge operation is thus allowed to be completed with a minimum purge amount.

Abstract: In an injection molding system, a molded part transport apparatus and a worker share an area to perform cooperative work. When a molded part check mode is valid, conforming product identification inspection of a molded part is performed in an area where the worker works, and molded part sorting means sorts the molded part on the basis of a result of the inspection. As a result, the conforming product identification inspection of the molded part can be performed and the molded part can be sorted with the safety of the worker is maintained.

Abstract: Comparison and analysis between stored image data which is obtained by performing image-taking by a mold image-taking means in a state in which a mold surface is clean and stored and taken image data which is obtained by performing image-taking by the mold image-taking means are performed and a cleaning part of the mold is specified to clean the mold. Accordingly, an image of a region, in which fouling and residues of fine dust may be generated, of the mold surface can be fully taken and generation of waste in a cleaning operation can be prevented.

Abstract: An injection molding system includes an injection molding machine and a data management device. The injection molding machine includes an abnormality detection unit that detects an abnormality of a pressure on a resin in an injection cylinder, and the data management device includes a data storage unit that stores abnormality detection data on the resin pressure, including a resin pressure value obtained when the abnormality of the resin pressure is detected by the abnormality detection unit and the time and date of detection of the abnormality. Further, the injection molding machine includes a data analysis unit that analyzes the abnormality detection data and a determination unit that determines whether or not to output an alarm, based on the result of analysis of the abnormality detection data.

Abstract: A hybrid drive device includes a speed change mechanism, a motor drivingly coupled to an input shaft, and a clutch interposed between an engine and an input shaft. Upon engine start during engine traveling, the clutch is engaged, and rotation of the engine is increased. A control device of the hybrid drive device includes start upshift control means that, according to the engagement control of the clutch upon engine start, upshifts the speed change mechanism to output inertia torque. Thus, when the engine is started, output torque as the sum of driving torque of the motor and the inertia torque is output to the driving wheel, which reduces hesitation upon engine start.

Abstract: Upon the occurrence of the abnormality that the inverter for driving the motor is in the one-phase short circuited state, this inverter is stopped in the three-phase short circuited state and sets the execution torque by subtracting the counter electromotive force application torque that is applied the driveshaft due to the counter electromotive force generated by rotation of the motor and the steering angle application torque corresponding to the steering angle from the torque demand according to the step-on amount of the accelerator pedal. The engine and the inverter for driving the motor is controlled so that the vehicle is driven with the set execution torque. This enables the driving force output to the driveshaft from the engine and the motor to be in accordance with the torque demand.

Abstract: A notched region in which the outer periphery of a screw flight is cut out is provided in a molding material feed screw. A wedge-shaped portion is formed by both a front wall surface of the screw flight and a wall surface of the boundary where the outer periphery of the screw flight is cut out. As a result of rotation of the molding material feed screw, since the wedge-shaped portion advances while pushing aside resin pellets located in the front thereof in two lateral directions of the front wall surface of the screw flight and the wall surface of the boundary where the outer diameter of the screw flight is cut out, entrapment of the resin pellets between the edge of a material supply port of a molding material supply device and the outer periphery of the screw flight is avoided as much as possible.

Abstract: Screw rotation speeds and screw rotating torques are measured at predetermined time intervals during metering and substituted into a previously-assumed function to determine a maximum screw rotating torque at each screw rotation speed. An allowable upper limit of screw rotating torque is set for each screw rotation speed on the basis of the determined maximum screw rotating torque. If a screw rotating torque exceeding the allowable upper limit is detected during metering after the allowable upper limit is set, the screw rotation is stopped or changed.
