Punch Scrap Storage Box Airflow Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses, the storage efficiency of punch scraps is reduced due to their concentration around the scrap dropping point, leading to spilling and limited storage capacity, which complicates the layout and operation of punch processing units.
Innovation Solution
The implementation of an air-blower or air-sucker system to convey punch scraps from the punch processor to the storage box, dispersing them uniformly and preventing spilling by controlling airflow direction and intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the punch scrap storage box is arranged just under the punch processing unit to ensure large storage capacity, then the storage capacity is improved, but the layout flexibility is reduced and work efficiency is lowered due to deep box requirement and limited space
Solution Approach 1:
The punch processing unit is extracted from its conventional position directly above the storage box and relocated to the downstream side of the sheet post-processing unit. This separation allows the storage box to be positioned independently, improving both accessibility and layout flexibility while maintaining adequate storage capacity.
Solution Approach 2:
The storage box is repositioned from a vertical arrangement (directly under the punch unit) to a lateral arrangement (adjacent to the punch unit on the side). This dimensional change in spatial configuration allows for better accessibility and layout flexibility without compromising storage capacity.
2Length of stationary object
If the punch scraps are allowed to heap naturally around the scrap dropping point, then the storage box can be shallow, but the storage efficiency is reduced and scraps spill out due to concentration at center
Solution Approach 1:
A vibration mechanism is introduced to the storage box to actively disperse and flatten the heaped punch scraps. This prevents concentration at the center, eliminates spilling, and maximizes storage efficiency while allowing the use of shallower storage boxes.
3Area of stationary object
If the punch processing unit is arranged in the inner part of the sheet post-processing unit, then the layout is compact, but the storage box must also be arranged in the inner part reducing work efficiency and limiting layout options
Solution Approach 1:
The punch processing unit is extracted from the inner part arrangement and repositioned to the downstream side. This allows the storage box to be placed in a more accessible location, improving operational efficiency while maintaining compact overall design.

AI summary
A sheet processing device having punch processing device(s) for punch-processing on a conveyed sheet member and a punch-scrap storage box for storing punch scraps therein that are produced by the punch processing and dropped from the punch-processing device(s) having an increased storing capacity of punch scraps, including a punch-scrap storage box constituting an air distribution duct having a punch-scrap suction inlet and an air discharge outlet; and air-sucking device(s) (fan) arranged on the most downstream side in the air discharge outlet of the air flowing direction for conveying the punch scraps produced by the punch processing device(s). Air is sucked by the fan so as to catch the punch scraps with punch-scrap separating device(s) arranged on the upstream side of the air flowing direction of the fan so that the punch scraps are heaped within the punch scrap storage box.
