Abstract

An object is to provide a production status display apparatus which can grasp the production status of each injection molding machine (Mi) and recognize the production end time. On a screen of a display apparatus connected to controllers of a plurality of molding machines, molding machine identifiers for identifying the individual molding machines are displayed. A scheduled progress status of each molding machine, which is determined on the basis of a molding cycle and a scheduled number of products to be produced from the present time, is also displayed, while being related to the corresponding molding machine identifier, with the present time used as a reference. Since the scheduled progress status of each molding machine is displayed on the screen, it can be judged at a glance which molding machine will end production earlier than others. Accordingly, the production status of each molding machine can be grasped, and the production end time can be recognized. As a result, a production plan can be made easily, and an efficient production process can be planned.

Claims

1. A production status display apparatus for molding machines comprising,

a screen of a display apparatus, which is connected to controllers of a plurality of molding machines, displays;

(a) a plurality of molding machine identifiers which identify the individual molding machines on the screen; and

(b) a scheduled progress status of each molding machine, which is determined on the basis of a molding cycle and a scheduled number of products to be produced from the present time, and is related to the corresponding molding machine identifier, with the present time used as a reference.

2. A production status display apparatus for molding machines according to claim 1, wherein an actual production status based on an actual number of products produced by each molding machine in a period from start of production to the present is displayed on the screen to be located adjacent to the scheduled progress status.

3. A production status display apparatus for molding machines according to claim 1, wherein a production end time is calculated on the basis of the scheduled progress status.

4. A production status display apparatus for molding machines according to claim 1, wherein when production is continued after a time at which the actual production status reaches the scheduled number of products to be produced, an excessive production status is displayed.

5. A production status display apparatus for molding machines according to claim 1, wherein end of production is predicted in relation to the present time on the basis of a non-defective product production ratio in a predetermined past period, and the predicted end of production is displayed.

6. A production status display apparatus for molding machines according to claim 1, wherein a delivery time of products molded by each molding machine is displayed, while being related to each molding machine.

7. A production status display apparatus for molding machines according to claim 1, wherein end of production is predicted and displayed on the basis of a predicted stoppage time over which operation of each molding machine is predicted to stop.

8. A production status display apparatus for molding machines according to claim 1, wherein the scheduled progress status is displayed by use of a bar graph element, while being related to each molding machine.

9. A production status display method for molding machines comprising, on a screen of a display apparatus connected to controllers of a plurality of molding machines, molding machine identifiers which identify the individual molding machines are displayed;

and a scheduled progress status of each molding machine, which is determined on the basis of a molding cycle and a scheduled number of products to be produced from the present time, is displayed, while being related to the corresponding molding machine identifier, with the present time used as a reference.
