Abstract

A press machine includes a machine body that is able to press a workpiece and a notifier that notifies an operator of the operation of the machine body or the state of the workpiece in advance using at least one of a sound and light selected in accordance with the operation of the machine body.

First claim

The invention claimed is:

1. A press machine comprising:
a machine body that is able to press a workpiece;
a storage that stores a machining program;
a body controller to control the machine body in accordance with the machining program; and
a notifier including a controller and further including a speaker and/or a lamp; wherein
the machining program includes code associated with a future operation of the machine body; and
the controller included in the notifier controls the notifier to notify an operator of the future operation of the machine body in advance of the future operation of the machine body using the speaker and/or the lamp to output at least one of a sound and a light selected based on the code associated with the future operation of the machine body.

2. The press machine of claim 1 , wherein the controller included in the notifier controls a signal indicating the sound; and
the notifier includes the speaker that outputs the sound based on the signal.

3. The press machine of claim 2 , wherein
the machining program includes information about the workpiece; and
the controller included in the notifier sets a type of the sound to be outputted from the speaker in accordance with the information about the workpiece.

4. The press machine of claim 2 , further comprising at least one of a sensor that detects a current operation of the machine body and a sensor that detects a current situation of the workpiece; wherein
the controller included in the notifier outputs the sound from the speaker based on a detection result of the at least one of the sensor that detects the current operation of the machine body and the sensor that detects the current situation of the workpiece.

5. The press machine of claim 2 , wherein the controller included in the notifier sets at least one of a timing when the sound is outputted from the speaker and a type of the sound to be outputted from the speaker based on information about the operator.

6. The press machine of claim 2 , wherein the controller included in the notifier provides notification of a side on which machining will be performed of a machining region of the machine body by controlling a direction in which the sound is outputted from the speaker.

7. The press machine of claim 2 , wherein
the speaker includes speakers disposed on both sides of a machining region of the machine body; and
the controller included in the notifier provides notification of a side on which machining will be performed of the machining region of the machine body by outputting the sound selectively from the speakers on the both sides.

8. The press machine of claim 2 , wherein the controller included in the notifier adjusts at least one of frequency characteristics and damping characteristics of the sound to be outputted from the speaker.

9. The press machine of claim 2 , further comprising an additional storage that stores a sound list indicating candidates of the sound; wherein
the controller included in the notifier selects, from the sound list, a sound to be outputted from the speaker.

10. The press machine of claim 2 , wherein the sound comprises at least one of a voice and a melody.

11. The press machine of claim 2 , wherein
the notifier includes a display; and
the notifier notifies the operator of the future operation of the machine body in advance by displaying an image indicating the future operation of the machine body on the display in synchronization with the at least one of the sound or the light.

12. The press machine of claim 2 , wherein the notifier outputs at least one of a phase-adjusted sound and a rhythm sound so that at least one of an operation sound of the machine body and an ambient sound is canceled out.

13. The press machine of claim 1 , wherein the sound comprises at least one of a voice and a melody.

14. The press machine of claim 1 , wherein the notifier includes a display; and the notifier notifies the operator of the future operation of the machine body in advance by displaying an image indicating the future operation of the machine body on the display in synchronization with the at least one of the sound or the light.

15. The press machine of claim 1 , wherein the notifier outputs at least one of a phase-adjusted sound and a rhythm sound so that at least one of an operation sound of the machine body and an ambient sound is canceled out.
