Pile Receivers TRIZ Cases

A sheet conveying device uses wall member through holes to create inclined surfaces that absorb acoustic noise via Helmholtz resonance.

A reversing guide redirects sheet flow to enable vertical stacking of feed and discharge trays within a compact housing.

A pivotable upper conveying guide swings to open the sheet path.

Separating the drive mechanism from the stack holding unit reduces friction and wear while eliminating high compressive forces.

Merging support functions into one clipboard reduces drive complexity while preventing small blanks from tilting during high-speed stacking.

Self-positioning movable guides secure load-bearing rods to eliminate manual tightening and reduce production interruptions.

Movable filler withdraws envelopes from vertical stacker and feeds them into mail trays, reducing manual collection workload.

A paper guide surface with a protruding part supports cut slips at an angle to enable automatic discharge via the next recording sheet.

Dynamic elevation control adjusts the discharge tray position based on curl detection, preventing rolling and buckling of curled sheets.
