Abstract: There is provided an apparatus for taking out a molded product that facilitates setting of a user-set lower limit value while maintaining on-off control. A negative pressure control portion includes a determining portion for determining a pressure valve resumption time period that is used to resume a suctioning operation such that an inflection point does not become lower than a user-set lower limit value. The negative pressure control portion continuously performs an off operation, which is performed to keep a pressure valve closed until the pressure valve resumption time period elapses after the suctioning operation is stopped, and an on operation, which is performed to open the pressure valve and keep the pressure valve open until a negative pressure reaches a stable value or an upper limit set value, until suctioning of a molded product is canceled.

Abstract: A control valve mechanism includes a three-port valve provided at a front conduit section of a conduit line and a two-port valve provided at a rear conduit section of the conduit line, the two-port valve is controlled to be in an opened state during the suctioning operation and to be in a closed state during the releasing operation. The three-port valve is controlled to be in a first state in which negative pressure generated by a vacuum generator is supplied to one or more suction pads during the suctioning operation, and to be in a second state in which the supply of the negative pressure generated by the vacuum generator is blocked form a negative pressure confining section arranged between the three-port valve and the two-port valve and to open the inside of the one or more suction pads to the atmosphere during the releasing operation.

Abstract: 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.

Abstract: 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.
