Mounting Control for Feeder Slot Restrictions and Loader Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the mounting system, the feeder may not be properly attached to or detached from certain slots by the loader due to operator instructions or slot states, leading to unintentional stoppage of the moving work device when the attachment and detachment instructions in the instruction list cannot be followed.
Innovation Solution
A management device that creates an instruction list based on prohibition information about which attachment sections the loader cannot attach or detach from, ensuring that only valid attachment and detachment instructions are executed, thereby preventing the loader from stopping unintentionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the instruction list includes attachment and detachment instructions for all slots, then the completeness of the instruction list is improved, but the moving work device may stop unintentionally when it cannot access certain slots
Solution Approach 1:
The instruction list is segmented into multiple subsets, each corresponding to different operable slot combinations. Instead of maintaining one complete instruction list that may cause stoppages, the system divides instructions into groups that can be executed based on current slot accessibility, allowing the loader to continue operating with available instructions rather than stopping when encountering inaccessible slots
Solution Approach 2:
The instruction list becomes dynamic rather than static. The system automatically generates and updates instruction lists based on real-time slot states and loader operability. When slot accessibility changes, the instruction list is regenerated to reflect current conditions, ensuring the loader always has valid instructions to execute without unnecessary stoppages
2Extent of automation
If the loader automatically attaches and detaches feeders from all slots, then the automation level is improved, but the system cannot handle operator restrictions or slot state limitations
Solution Approach 1:
The system changes the parameter of instruction validity based on slot states and operator restrictions. Instead of fixed automatic instructions, the system evaluates slot accessibility parameters and generates instructions only for valid target slots. This allows automatic operation to adapt dynamically to changing conditions while maintaining high automation levels
Solution Approach 2:
The system implements feedback mechanisms where slot states and loader operability information are continuously monitored and fed back to the instruction generation process. This feedback loop enables the automatic system to adjust its behavior based on current conditions, generating appropriate instruction lists that respect operator restrictions and slot states while maintaining automation

AI summary
There is provided a management device used in a mounting system including multiple mounting-related devices in which a member related to mounting of a component is attached to one or more attachment sections, and a moving work device that moves between the multiple mounting-related devices to automatically attach and detach the member to and from the attachment sections, the management device including, when acquiring prohibition information including information on the attachment sections to and from which the member is not attachable and detachable by the moving work device from the mounting-related device, a management control section that creates an instruction list based on the prohibition information, in which an attachment and detachment instruction of the member for the attachment sections other than the attachment sections to and from which the member is not attachable and detachable is registered, and causes the moving work device to execute attachment and detachment processing of the member based on the instruction list.
