Abstract

A injection molding system extracts molding data and inspection data having a difference between a first position information of a conveyance part where a molded article produced by an injection molding apparatus is picked up by a conveyor device and a second position information of the conveyance part where the molded article is inspected by an inspection device is equal to a predetermined distance between a pickup position and an inspection position, and stores the molding data and the inspection data in association with each other as a set. This configuration makes it possible to associate molding data of an injection molding apparatus when producing a molded article and inspection data with each other to control the quality of molded articles.

First claim

1 . An injection molding system comprising:
an injection molding apparatus; a conveyance means configured to convey a molded article produced by the injection molding apparatus; an inspection means configured to inspect the molded article conveyed by the conveyance means; a conveyance position detection means configured to detect a position of a conveyance part of the conveyance means; and a data storage means configured to store data, wherein the data storage means stores:
molding data when the injection molding apparatus produces the molded article; and
first position information of the conveyance part that is a position of the conveyance part detected by the conveyance position detection means when the produced molded article is picked up by the conveyance means,
the molding data and the first position information of the conveyance part being stored in association with each other as a set, a plurality of sets of the molding data and the first position information being stored in the data storage means,
wherein the data storage means stores:
inspection data when a molded article is inspected by the inspection means; and
second position information of the conveyance part that is a position of the conveyance part detected by the conveyance position detection means when the molded article is inspected by the inspection means,
the inspection data and the second position information of the conveyance part being stored in association with each other as a set, a plurality of sets of the inspection data and the second position information of the conveyance part being stored in the data storage means, and
wherein the data storage means extracts a set of the molding data and the first position information of the conveyance part and a set of the inspection data and the second position information of the conveyance part of which the first position information and the second position information of the conveyance part have a difference equal to a predetermined distance between a pickup position where the molded article is picked up by the conveyance means and an inspection position where the molded article is inspected by the inspection means, respectively from the plurality of sets of the molding data and the first position information of the conveyance part and the plurality of sets of the inspection data and the second position information of the conveyance part, and stores the molding data included in the extracted set of the molding data and the first position information and the inspection data included in the extracted set of the inspection data and the second position information in association with each other.

2 . An injection molding system comprising:
an injection molding apparatus; a conveyance means configured to convey a molded article produced by the injection molding apparatus; an inspection means configured to inspect the molded article conveyed by the conveyance means; a time detection means configured to detect current time; and a data storage means configured to store data, wherein the data storage means stores:
molding data when the injection molding apparatus produces a molded article; and
first time information that is a time detected by the time detection means when the produced molded article is picked up by the conveyance means,
the molding data and the first time information being stored in association with each other as a set, a plurality of sets of the molding data and the first time information being stored in the data storage means,
wherein the data storage means stores:
inspection data when a molded article is inspected by the inspection means; and
second time information that is a time detected by the time detection means when the molded article is inspected by the inspection means,
the inspection data and the second time information being stored in association with each other as a set, a plurality of sets of the inspection data and the second time information being stored in the data storage means, and
wherein the data storage means extracts a set of the molding data and the first time information and a set of the inspection data and the second time information of which the first time information and the second time information have a difference equal to a moving time required to move between a pickup position where the molded article is picked up by the conveyance means and an inspection position where the molded article is inspected by the inspection means, respectively from the plurality of sets of the molding data and the first time information and the plurality of sets of the inspection data and the second time information, the moving time being obtained based on a distance between the pickup position and the inspection position and a conveyance speed of the conveyance means, and stores the molding data included in the extracted set of the molding data and the first time information and the inspection data included in the extracted set of the inspection data and the second time information in association with each other.

3 . The injection molding system according to claim 1 ,
wherein the inspection means includes an inspection device configured to inspect the molded article and a moving means configured to move the molded article, wherein the moving means moves the molded article from the inspection position to the inspection device, and wherein the inspection device inspects the molded article moved by the moving means and obtains the inspection data.

4 . The injection molding system according to claim 3 ,
wherein the moving means is a robot.
