  • Patent number: 11228649
    Abstract: There are provided a molded product manufacturing system that can be easily adapted to IoT and an apparatus for taking out a molded product that can promote adaptation of the molded product manufacturing system to IoT. A molded product manufacturing system includes an injection molding machine, an apparatus for taking out a molded product, and one or more peripheral devices arranged around the apparatus to operate together during operation of the apparatus. The apparatus includes a communication unit operable to transmit internal data to an external server via a communication network. The communication unit of the apparatus transmits external data, which is output from the one or more peripheral devices, to external servers together with information on a die.

  • Patent number: 10086546
    Abstract: An apparatus for taking out a molded product, includes: a transverse frame disposed above a resin injection molding machine to extend in a transverse direction, which is orthogonal to a longitudinal direction; an orthogonal frame supported by the transverse frame so as to be movable at least in the transverse direction; a vertical arm provided at the orthogonal frame so as to be movable up and down at least in the vertical direction; and a holding member provided at a distal end portion of the vertical arm to hold a resin molded product formed by the resin injection molding machine. The vertical arm is disposed so as to be inclined such that the axis line of an elevating shaft of the vertical arm forms an acute angle with respect to a perpendicular extending in the vertical direction.

  • Patent number: 8072173
    Abstract: Disclosed a servo motor monitoring apparatus including: a magnetic pole position calculating member to extract a magnetic pole position signal of the servo motor from a motor drive line connected to the servo motor; a present position signal inputting member to receive an input of a present position signal from the position detecting member attached to the servo motor; and a monitoring member to compare operations of the servo motor based on two types of signals of the magnetic pole position signal and the present position signal of the servo motor, and to output a stop instruction signal for cutting off a power supply to the servo motor when detecting disagreement.
