Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation methods fail to accurately model the behavior of workpieces placed near a transporting surface of a carrier, particularly when released from a position above the surface, as they do not account for the master-slave relationship and processing of multiple workpieces on a conveyor.
Innovation Solution
A simulator that estimates the behavior of a system with a carrier and processing device, using a creating unit to create a three-dimensional virtual space, a tracking unit to update positions of targets on the transporting surface, and an instruction generation unit to generate control instructions based on target positions, associating targets with the transporting surface when within a predetermined range.

1Measurement precision
If existing simulation methods are used to model workpiece behavior on conveyors, then the simulation can handle basic transporting operations, but it cannot accurately model workpieces placed near or above the transporting surface
Solution Approach 1:
The simulation model dynamically switches between different workpiece states (in-transit, placed-on-surface, placed-near-surface) based on real-time position and velocity conditions. This allows the system to adapt its behavior model according to the workpiece's actual state, enabling accurate simulation of both conventional and novel placement scenarios.
Solution Approach 2:
The invention changes key parameters such as the placement distance threshold and velocity threshold to distinguish between different workpiece placement scenarios. By adjusting these parameters, the simulation can accurately represent various physical conditions including workpieces placed directly on the surface versus those placed near or above the surface.
2Quantity of substance
If the simulation tracks multiple workpieces on a conveyor, then comprehensive system behavior can be analyzed, but the complexity of defining master-slave relationships increases
Solution Approach 1:
The simulation divides the conveyor system into discrete segments or zones, with each workpiece tracked independently through these segments. This segmentation approach allows multiple workpieces to be managed separately while maintaining clear master-slave relationships, reducing overall system complexity.
Solution Approach 2:
Each workpiece in the simulation autonomously determines its own state and behavior based on its position and velocity relative to the conveyor, rather than requiring centralized control logic for every interaction. This self-service approach simplifies the overall control structure while enabling accurate multi-workpiece tracking.
3Ease of operation
If workpieces are released from a position above the transporting surface, then pick-and-place operations can be simulated, but the workpiece may not be accurately associated with the conveyor
Solution Approach 1:
The simulation performs preliminary checks on workpiece position and velocity before finalizing the placement association with the conveyor. By evaluating these conditions in advance, the system ensures that workpieces released from above the surface are correctly associated with the conveyor, maintaining reliability while enabling pick-and-place operations.
Solution Approach 2:
The simulation continuously monitors workpiece position and velocity, providing feedback to determine when and how to associate the workpiece with the conveyor. This feedback mechanism ensures accurate association even when workpieces are released from elevated positions, maintaining reliable tracking throughout the operation.

AI summary
The simulation reflects the actual behavior of a target in an application involving a target near a transporting surface of a carrier instead of being placed directly on the transporting surface. A simulator includes a creating unit that virtually creates a system in a three-dimensional virtual space, a tracking unit that updates positions of targets on the transporting surface in the three-dimensional virtual space based on a corresponding movement of the carrier, and updates a position of a target picked up by the processing device in association with a behavior of the processing device, and an instruction generation unit that generates a control instruction for the behavior of the processing device based on the position of each target. When the processing device places a target within a predetermined range from the transporting surface, the tracking unit associates the target with the transporting surface and updates a position of the target.
