Solution Overview
Problem
Operators face difficulties in intuitively setting the slide operation of a press machine to avoid interference with the movement of an accessory device, requiring a high skill level, especially in servo press machines where slide operations can be arbitrarily changed.
Innovation Solution
A press machine with a user interface and display that visually represents the relationship between slide and movement operations using annular and arc-shaped images, allowing operators to easily recognize and settable relationships between slide and movement operations, including determining slide stop and delay times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional tabular interface is used for setting operation timing, then the setting process can be completed, but it becomes difficult for operators to intuitively recognize the margin to avoid interference between slide operation and accessory device operation
Solution Approach 1:
The patent transforms the conventional one-dimensional tabular interface into a two-dimensional visual display that maps crank angle positions and operation timing spatially. The display shows the slide operation waveform and accessory device operation waveform on the same temporal-spatial axis, allowing operators to visually perceive the temporal relationship and margin between operations, thereby resolving the information loss problem while maintaining ease of operation.
Solution Approach 2:
The patent creates a visual copy of the actual operational timing relationship by displaying waveform representations of the slide operation and accessory device operation. This visual copy allows operators to see the actual timing margin without needing to mentally calculate or interpret numerical values from tables, making the interference avoidance margin immediately perceivable.
2Adaptability or versatility
If the interface depends on operator skill level for setting, then experienced operators can set operations, but the setting may still differ from intent and requires higher skill for servo press machines with arbitrary slide operations
Solution Approach 1:
The patent implements visual feedback by displaying the actual timing relationship between slide operation and accessory device operation on the interface. This feedback mechanism allows operators to immediately see whether their setting creates the intended margin or may cause interference, enabling self-correction and ensuring setting accuracy regardless of operator skill level. The visual confirmation acts as real-time feedback that guides operators to achieve correct settings.
Solution Approach 2:
The patent uses color coding to visually distinguish different operational states and timing margins. By applying color changes to indicate safe margins versus potential interference zones, the system provides intuitive visual guidance that reduces dependency on operator skill and ensures consistent, accurate settings across different operators and machine types.

AI summary
A press machine includes a display that displays a plurality of images, and a processor that generates a plurality of images corresponding to a slide operation and a movement operation. The plurality of images include a first image having an annular shape, a second image having an arc shape, and a third image. A first region of the second image represents a movement time required for the movement operation, a third region represents a stop time required for a slide stop process, and a second region represents a delay time until the slide stop process starts after the movement time elapses. The processor displays the third image on the display as a determination element for determining whether the slide operation and the movement operation are settable in a relationship between the slide operation and the movement operation based on an input from the user interface.
