Abstract

When collecting data in connection with operational physical values from a plurality of injection molding machines by means of a direct numerical control computer system incorporated in an LAN, for example, when collecting a quality control data, the direct numerical control computer system is allowed to specify a collection starting time and a collection terminating time of the data for the respective injection molding machines. With reference to the condition thus specified the data is communicated to the direct numerical control computer system from the respective injection molding machines.

Claims

1. A method of collecting data of a group of injection molding machines for collecting data in connection with operational physical values from a plurality of injection molding machines by means of a direct numerical control computer system incorporated in an LAN system,

a method of collecting data of a group of injection molding machines comprising of steps of,

selectively specifying a collection starting time and a collection terminating time of data for the respective injection molding machines by means of a direct numerical control computer system, and

responsive to the specifying step, communicating the data to the direct numerical control computer system from the respective injection molding machines in accordance with a specified condition.

2. A method of collecting data of a group of injection molding machines as claimed in claim 1, wherein the data is a data for a quality control.

3. A method of collecting data of a group of injection molding machines as claimed in claim 1, wherein a kind of data to be collected and/or a sampling interval for collecting the data are previously set by the direct numerical control computer system.

4. A method of collecting data of a group of injection molding machines as claimed in claim 3, wherein the sampling interval is set based on a number of molding shots.
