Abstract

An injection molding system includes a program control section installed outside injection molding machines. The program control section includes a program file section that stores a plurality of different programs in the form of files, and a program transfer section that selects a computer program from the program file section and transfers the selected computer program to the controller of an arbitrary injection molding machine when the arbitrary injection molding machine is operated. Only when an injection molding machine is operated, a program (control program) for operating the injection molding machine is selected from the program file section of the program control section, and the thus-selected program is transferred to the corresponding controller by the program transfer section.

Claims

1. An injection molding system comprising:

one or more injection molding machines, each injection molding machine equipped with a controller that operates in accordance with a computer program, wherein a program control section is installed outside said injection molding machines,

said program control section comprising a program file section that stores a plurality of different computer programs in the form of files, and

a program transfer section that selects a computer program from said program file section and transfers the selected computer program to the controller of an arbitrary injection molding machine when said injection molding machine is operated, wherein the computer program transferred to said controller of said arbitrary injection molding machine is erased upon completion of operation of the corresponding molding machine.

2. An injection molding system according to claim 1, wherein said controller includes a memory that can temporarily store the computer program transferred from said program transfer section.

3. An injection molding system according to claim 1, wherein the computer program transferred to said controller is replaced with a newly transferred computer program.

4. An injection molding system according to claim 1, wherein said computer program is a control program.

5. An injection molding system according to claim 1, wherein said controller and said program transfer section are connected with each other in order to perform intercommunications between said controller and said program transfer section.

6. An injection molding system according to claim 1, wherein the computer program to be transferred to said controller is selected by said program control section.

7. An injection molding system comprising:

one or more injection molding machines, each injection molding machine equipped with a controller that operates in accordance with a computer program, wherein a program control section is installed outside said injection molding machines,

said program control section comprising a program file section that stores a plurality of different computer programs in the form of files, and a program transfer section that selects a computer program to be transferred from said program file section and transfers the selected computer program to the controller of an arbitrary injection molding machine when said injection molding machine is operated, wherein the controller of the arbitrary injection molding machine selects said computer program to be transferred to the controller.

8. An injection molding system according to claim 7, wherein said controller includes a memory that can temporarily store the computer program transferred from said program transfer section.

9. An injection molding system according to claim 7, wherein a computer program transferred to said controller is replaced with a newly transferred computer program.

10. An injection molding system according to claim 7, wherein said computer program is a control program.

11. An injection molding system according to claim 7, wherein said controller and said program transfer section are connected with each other in order to perform intercommunications between said controller and said program transfer section.
