Abstract

A display unit of an injection molding machine that displays an order of operations of elements operating during clamp close or open of the injection molding machine, the display unit including a condition setting unit that sets a start condition of the operation; a group setting unit that sets the elements operating in conjunction with each other to be associated with the same group, based on the set start conditions; an order setting unit that sets the order of the operations of the elements associated with the same group, based on the set start conditions; and a display control unit that controls a display unit to display a field showing the group, and to display symbols indicating the operations of the elements associated with the groups in the fields, to show a before and after relationship in accordance with the set order of the operations.

First claim

What is claimed is:

1. A control device of an injection molding machine that displays an order of operations of a plurality of elements operating during clamp close or open of the injection molding machine, the control device configured to:
set, with respect to a plurality of elements operating during either one of the clamp close or open, an operation start condition for each element;
associate one element and another element that operates in conjunction with an operation of said one element with one group and associate still another element that does not operate in conjunction with the operation of the one element with another group, based on the set operation start condition for each of the elements;
set an order of operations of the one element and the another element of the plurality of elements associated with the one group, based on the set operation start conditions for the one and another elements; and
control a display unit to display a field showing the one group and another field showing the another group and to display a symbol indicating an operation of said one element and a symbol indicating an operation of said another element in the field showing the one group in a manner of being related to each other in accordance with the set order of the operations of the one element and the another element of the plurality of elements, and also to display a symbol indicating an operation of said still another element in the another field showing said another group.

2. The control device of the injection molding machine according to claim 1 , wherein the control device is further configured to control the display unit to display lines providing connections between the symbol indicating the operation of the one element and the symbol indicating the operation of the another element that are displayed in the field indicating the one group.

3. The control device of the injection molding machine according to claim 1 , wherein the control device is further configured to control the display unit to display information indicating a direction of a passage of time.

4. The control device of the injection molding machine according to claim 1 , wherein the control device is further configured to:
display an order in which the field showing the one group and the another field showing the another group are displayed, based on start times of the operations of the plurality of elements that operate first in each group; and
control the display unit to display the fields field showing the one group and the another field showing the another group in a manner to show a before-and-after relationship according to the order in which the field showing the one group and the another field showing the another group are displayed.

5. The control device of the injection molding machine according to claim 1 , wherein
the operation of the one element is any one of an operation of a core of a mold, a mold closing operation, a mold opening operation, an ejector operation, a molded article unloading operation, and a signal output operation for outputting a signal from the injection molding machine to peripheral devices of the injection molding machine.

6. The control device of the injection molding machine according to claim 1 , wherein
the operation of the another element is any one of an operation of a core of a mold, a mold closing operation, a mold opening operation, an ejector operation, a molding cycle start operation, an injection operation, a pressure holding operation, a measurement operation, and a signal input operation for inputting a signal from a peripheral device of the injection molding machine to the injection molding machine.

7. The control device of the injection molding machine according to claim 1 , wherein
the operation of the one element is a set operation for installing a first core inside a mold, and the operation of the another element is a set operation for installing a second core inside a mold, or
the operation of the one element is a pull operation for returning the installation of the first core from the mold, and the operation of the another element is a pull operation for returning the installation of the second core from the mold.

8. The control device of the injection molding machine according to claim 7 , wherein
when an operation start condition for a set operation of the first core and an operation start condition for a set operation of the second core that operates in conjunction with the set operation of the first core are set, the control device is further configured to set an order of the pull operation of the first core and the pull operation of the second core to be the opposite of an order of the set operation of the first core and the set operation of the second core.

9. A display method of a control device that displays an order of operations of a plurality of elements operating during clamp close of clamp open of an injection molding machine, the display method comprising:
setting, with respect to a plurality of elements operating during either one of the clamp close or open, an operation condition for each element;
associating one element and another element that operates in conjunction with an operation of the one element with one group and associate still another element that does not operate in conjunction with the operation of the one element with another group, based on the set operation start condition for each of the elements;
setting an order of operations of the one element and the another element of the plurality of elements associated with the one group, based on the set operation start conditions for the one and another elements; and
controlling a display unit to display a field showing the one group and another field showing the another group and to display a symbol indicating an operation of the one element and a symbol indicating an operation of the another element in the field showing the one group in a manner of being related to each other in accordance with the set order of the operations of the one element and the another element of the plurality of elements, and also to display a symbol indicating an operation of the still another element in the another field showing the another group.

10. The display method of the control device according to claim 9 , further comprising controlling the display unit to display lines providing connections between the symbol indicating the operation of the one element and the symbol indicating the operation of the another element that are displayed in the field indicating the one group.

11. The display method of the control device according to claim 9 , further comprising controlling the display unit to display information indicating a direction of a passage of time.

12. The display method of the control device according to claim 9 , comprising:
displaying an order in which the field showing the one group and the another field showing the another group are displayed, based on start times of the operations of the plurality of elements that operate first in each group; and
controlling the display unit to display the field showing the one group and the another field showing the another group in a manner to show a before-and-after relationship according to the order in which the field showing the one group and the another field showing the another group are displayed.

13. The display method of the control device according to claim 9 , wherein
the operation of the one element is any one of an operation of a core of a mold, a mold closing operation, a mold opening operation, an ejector operation, a molded article unloading operation, and a signal output operation for outputting a si
