Punch Chip Receiving Structure for Clean Sheet Processor Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Punch chips accumulate in the storage unit of a sheet processing apparatus, necessitating regular disposal, which can be messy and inconvenient.
Innovation Solution
A removable storage unit with a movement unit and receiving unit that levels punch chips, preventing them from falling when the storage unit is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable storage unit is used to store punch chips, then ease of operation is improved, but punch chips may fall when the storage unit is removed
Solution Approach 1:
The receiving unit performs preliminary action by receiving and leveling punch chips before the storage unit is removed. The leveling process compacts the punch chips and creates a stable configuration that prevents them from falling during removal, thus resolving the contradiction between ease of operation and preventing harmful effects.
Solution Approach 2:
The receiving unit acts as an intermediary between the punching unit and the storage unit. It receives punch chips from the punching unit, levels them, and then allows the storage unit to be removed. This intermediary function ensures punch chips are properly prepared before storage unit removal, preventing them from falling while maintaining ease of operation.
2Productivity
If punch chips are allowed to accumulate in the storage unit, then productivity is improved, but punch chips may fall during removal
Solution Approach 1:
The receiving unit performs preliminary leveling action on accumulated punch chips before the storage unit is removed. This preliminary action compacts the accumulated chips and creates a stable configuration that prevents falling, allowing the storage unit to accumulate punch chips for improved productivity without the risk of chips falling during removal.
3Ease of operation
If the storage unit is made removable for easy disposal, then ease of operation is improved, but punch chips cannot be contained during removal
Solution Approach 1:
The receiving unit performs preliminary leveling action on punch chips before the storage unit is removed for disposal. This preliminary action compacts the chips and creates a stable configuration that prevents spillage during removal, thus maintaining both ease of operation through removability and containment of punch chips.
Solution Approach 2:
The receiving unit serves as an intermediary that processes punch chips before the storage unit is removed. It levels and stabilizes the chips, then allows the storage unit to be removed for easy disposal. This intermediary function ensures chips are contained during removal while maintaining the removability benefit.

AI summary
A sheet processing apparatus to process a sheet includes a first conveyance path, a punching unit, a storage unit, a movement unit, and a receiving unit. The punching unit punches the sheet conveyed in the first conveyance path. The storage unit is removable from the sheet processing apparatus and stores punch chips generated by the punching unit. The movement unit moves together with the punching unit in a direction parallel to a movement direction of the punching unit. The receiving unit is between the movement unit and the storage unit and receives the punch chips from the punching unit via the movement unit while supporting the movement unit. When the storage unit is removed in a state in which punch chips stored in the storage unit have accumulated to reach the receiving unit, some of the punch chips that have reached the receiving unit are leveled by the receiving unit.
