A system for taking out a molded product that does not require an operator to determine the sucking operation start time for a vacuum sucker by himself/herself by trial and error is provided. A controller includes a time interval measuring section configured to measure a time interval judging from an output from a pressure detector. The time interval measuring section measures a stable time interval since the pressure in a pipe reaches a predetermined pressure until a sucking operation start pressure is detected judging from an output from the pressure detector. The sucking operation start pressure indicates that a suction nozzle starts operation to suck up a molded product hereby the predetermined pressure is maintained. A sucking operation start time determining section of the controller determines a sucking operation start time such that a stable time interval is longer than a bias time interval, concurrently with movement control for a moving mechanism.

An injection molding system includes: an injection molding machine configured to operate in accordance with a command generated using a first language, and inject a molten material into a mold to mold a molded object; a robot configured to operate in accordance with a command generated using a second language, and convey the molded object; and a control device configured to control the injection molding machine and the robot. When determining that an error occurs in at least one of the injection molding machine and the robot, the control device transmits, to the injection molding machine, a command generated using the first language and for causing the injection molding machine to execute a return operation, and transmits, to the robot, a command interpretable by the second language and for causing the robot to execute a return operation, so as to cause the injection molding machine and the robot to execute the return operations.

Provided is an apparatus for taking out a molded product, which is capable of determining occurrence of a suction error and/or likelihood of a suction error of the molded product with high accuracy and of knowing a cause thereof. A pressure data storing section stores time-series pressure data from a pressure detector. A suction error cause determining section determines occurrence of a suction error and/or likelihood of a suction error of a molded product by a suction member on a basis of a time-series comparison result obtained by comparing the stored time-series pressure data with predetermined time-series reference data. When the suction error cause determining section determines the occurrence of the suction error and/or the likelihood of the suction error, the suction error cause determining section determines a cause of the occurring suction error and a solution therefor based on a time-series change pattern.

Provided is an apparatus for taking out a molded product capable of displaying information for facilitating adjustment on a display screen when performing adjustment for shortening a take-out time and a cycle time. The apparatus for taking out a molded product includes: a set condition storing section; an operation time counting section operable to count an actual operation time from a time when a plurality of set operations are started till a time when the operations are completed; an operation time storing section operable to store, the plurality of actual operation times counted by the operation time counting section; a display section including a display screen; a display control section; and a data computing section. The display control section displays on the display screen identification indications for a plurality of set operations, set values for the set operations, and the actual operations times stored in the operation time storing section.

An injection molding system includes: an injection molding machine configured to inject a molten material into a mold to mold a molded object; a tray moving unit configured to move a plurality of trays in a work area including a placement position; and a robot configured to place the molded object on a tray moved to the placement position among the plurality of trays. The tray moving unit moves a tray after placement, which is a tray on which the molded object is placed by the robot, from the placement position to a position different from the placement position in the work area, and moves a tray before the placement, which is a tray on which the molded object is not yet placed by the robot, from a position different from the placement position in the work area to the placement position.

An injection molding system includes: a first extruding member that extrudes a first molded article from a mold; a robot that transfers the first molded article extruded from the mold to an assembling position in relation to a second molded article in the mold; a second extruding member that extrudes the second molded article from the mold towards the first molded article retained at the assembling position by way of the robot, and assembles the second molded article to the first molded article; and a load detection unit that detects load applied to the second extruding member, in which defect discrimination of the first molded article, the second molded article, or an assembled state of the first molded article and the second molded article is performed, based on load detected by the load detection unit when the second molded article is assembled to the first molded article.

A method and a device for detecting a geometric feature of consistent molded parts takes into account the different stages of cooling due to different durations of transport of the individual removed molded parts to the inspection system. Both the geometric feature and the temperature of each molded part is measured. The detected geometric features are corrected using a calibration function taking into account the measured temperatures.

There is provided a control system for an apparatus for taking out a molded product, the apparatus performing appropriate operation when a collision occurs while a servo system control section is manually operated. When a collision detection section outputs an operation stop command, a deviation clearing section performs clearing operation to bring deviations in a servo system control section to zero with the servo system control section kept on. Positioning is completed as the deviations are brought to zero, which enables operation to be performed again. When a retracting operation is performed after the operation is stopped, servomotors are operated according to an operation command, which allows smooth retraction from the collision state.

A cycle time administration section 3 of an apparatus for taking out a molded product of the present invention includes: a measurement section 5 for measuring a cycle time for every one cycle of taking out a molded product; a setting and storing section 7 for setting and storing a target cycle time; a comparison section 9 for comparing the measured cycle time and the target cycle time for every one cycle; a counting section 11 for counting the number of times that the measured cycle times consecutively exceed target time, following the measured cycle time that has first exceeded the target cycle time, if it is determined that the measured cycle time has exceeded the target cycle time as a result of the comparing; and an outputting section 13 for outputting a detection signal if the counted number of times is more than n times.

An operation abnormality detection method for detecting an operation abnormality in a molding device having a movable part includes: acquiring a prescribed measured value relating to operation of the movable part and calculating, as statistical information, an average value of prescribed information values based on the prescribed measured values: calculating a first threshold and a second threshold; acquiring a current measured value and comparing a current information value based on the current measured value with the greater of the first threshold and the second threshold; and issuing a warning if the current information value at least exceeds the greater of the first threshold and the second threshold.
