Abstract

An injection molding machine and an additional injection device are provided such that a power interruption signal is output to a controller of the injection molding machine or the additional injection device on the destination when it is detected that a movable door is opened and a state of position confirmation means for the movable door is transmitted to the injection molding machine or the additional injection device on the destination through a communication line. Thus, the state of the position confirmation means can be transmitted and notified without decreasing maintainability.

First claim

The invention claimed is:

1. An injection molding system comprising:
an injection molding machine;
an injection molding machine controller for controlling the injection molding machine;
at least one additional injection device;
an additional injection device controller for controlling the additional injection device;
power interruption signal transmission means configured to transmit a power interruption signal between the injection molding machine controller and the additional injection device controller;
a communication line through which a state of position confirmation means for a movable door is transmitted between the injection molding machine controller and the additional injection device controller; and
notification means,
wherein the injection molding machine comprises at least one injection molding machine movable door and position confirmation means for the injection molding machine movable door, capable of detecting an open/close state of the injection molding machine movable door,
the injection molding machine controller outputs a power interruption signal to the additional injection device controller through the power interruption signal transmission means when it is detected by the position confirmation means for the injection molding machine movable door that the injection molding machine movable door is opened,
the additional injection device comprises at least one additional injection device movable door and position confirmation means for the additional injection device movable door, capable of detecting an open/close state of the additional injection device movable door,
the additional injection device controller outputs a power interruption signal to the injection molding machine controller through the power interruption signal transmission means when it is detected by the position confirmation means for the additional injection device movable door that the additional injection device movable door is opened,
the injection molding machine controller obtains the state of the position confirmation means for the additional injection device movable door through the communication line and/or the additional injection device controller obtains the state of the position confirmation means for the injection molding machine movable door through the communication line, and
the state of the position confirmation means for the additional injection device movable door and/or the state of the position confirmation means for the injection molding machine movable door is notified by the notification means.

2. The injection molding system according to claim 1 , wherein the notification means notifies a screen image based on the state of the position confirmation means for the additional injection device movable door and/or the state of the position confirmation means for the injection molding machine movable door.
